(54) Image forming apparatus


(57) An image forming apparatus is provided. The image forming apparatus includes a heating roller (51) having an electrode (513) to receive power disposed at an outer circumference thereof and a connection unit to supply the power to the heating roller via the electrode. The connection unit includes a connection member (531) connected to the electrode, the connection member being rotated along with the heating roller, an annular friction bush (532) disposed at the connection member, and at least one wire (533b) having one fixed end and the other end contacting an outer circumference of the friction bush. The connection member is rotated along with the heating roller, and therefore, no friction occurs between the electrode and the connection member, thereby preventing damage to the electrode.
